Have used the Air Fryer, Oven and Convection Oven features and am very pleased.  Love the option of being able to steam clean. Have owned this for a week now and still getting used to all the bells and whistles.  Have made use of the Air  Fryer, Oven, and Conventional Oven ... all worked very well.  The only drawbacks are that you have to purchase Air Fryer rack and Broiler Pan separately, and you cannot purchase a stovetop grid to switch out the 6" wide griddle.  Luckily, I was able to find Air Fryer racks that were far more affordable and offered 2 different sizes.  All in all, a nice appliance.
